2 Claims. (Cl. 15638) This invention relates to closures, especially onthe plane indicated by the, line VIIT-PVII of closures for windows ofbuildings, and particularly Fig. 6, viewed in the direction of thearrows at the closures consisting largely of a sheet or sheets ends ofthe line; Fig. 8 is a fragmentary detail of pervious material supportedby a skeleton View showing a connection between the inner and frame.outer sections of a window closure; Fig. 9 is a B0 A principal object ofthis invention is the prcdetail View corresponding to Fig. 4 but showingvision of a closure of the type described which a modified form ofpervious material attaching will form a complete closure of an openwindow means; Fig. 10 is a top plan View partly in section so that therewill be no opportunity at any point of a screen and window casing,illustrating the fit- "10 for insects of any considerable size to pass.ting of a wooden frame screen therein; Fig. 11 is 65 A further object ofthe invention is a closure an end view illustrating the manner in whichthe of the type specified, so constructed that the perbottom of thescreen of Fig. 10 contacts with the vious material forming the majorportion thereof window sill. may be quite readily applied, renewed, orre- In Fig. 1, a two part window closure has been 11.-

of window closure; Fig. 7 is a cross-sectional view stantially circularcross-section, is attached by 1m any appropriate means, such assoldering or welding, to the bottom rail 5 of section B, and another rod16 on the top rail 8 of section B; and a corresponding rod 17 at thebottom of section A; and a correspondnig rod 18, shown in Fig. 1 on thetop rail 4 of section A.

The pervious material, such as 13 and 14, is cut of the proper size, andthen laid fiat upon the section to which it is to be attached, then oneach of the rods such as 17, 18, 19, and 20 as shown in Fig. 1, a troughshaped retaining member is pushed down in place. These trough shapedmembers are designated 21, 22, 23, and 24', and are shown clearly incross-section in Fig. 5, in which 21 and 23 are most clearly shown onsection A. This construction is such that the pervious material may beremoved, or renewed, or replaced in case conditions necessitate achange.

This is especially necessary in the case of window closures used asventilators and covered with ,a pervious material such as cotton clothwhich becomes discolored and its pores filled with dust, so that atintervals it is necessary to remove, clean, and then replace it, or toremove and to replace it with new material. With applicants constructionit is very easy to make the change.

Each of the slides or sections A and B have a shoulder member, as 24 and25, attached thereto. These shoulder members are each designed to bearagainst the inside face of the bottom rail of the lower sash of awindow. Their position in relation to the lower rail 26 of a window sashis clearly shown by Fig. 5. The rail has its lower face 27 in contactwith the shoulder member 25 atthe point 28 and the inside face contactswith the shoulder member 25 at the point 29. At the same time, theinside face of the lower rail 26 contacts with the shoulder member 24 atthe point 30.

By reference to Figs. 1, 2, and 5 it will be seen that the section B,that is, the outside section is slightly longer than the section A, thatis, the inside section, so that the closure is supported by the outsidesection B resting on the sill 31 as at the point 32.

By reference to Fig. 3 it will be seen that the section B has an endextension 33 to the side rail '7 which extension is bent toward theplane of the section A and has its end surface in a plane passingthrough the inside surface of the section A, as shown by Fig. 3, so thatthe extension 33 of section B rests against the front stop 34 of thewindow casing and is on a line with the surface of rail 2 of section Awhich rests against the front stop 35.

l the rail 2, tightly against the front stop 35. The

right hand end of the closure bears, by means of the extension 33,tightly against the stop 34. At the top of the screen the shoulder 25bears against the lower rail 26 of the lower sash along the line 29, andsection A bears against the rail 26 along the line 30. Along the foursides of the screen there is no opportunity for insects to pass. Thepervious material 13 of section A is, of course, slightly separated fromthe pervious material 14 of section B, but the entrance of insectsthrough the space designated 37 in Fig. 5 is prevented, as best shown inFig. 3, by the pervious material contacting portion 38 of section Bbeing turned over to contact with the pervious material 13 0f section A,and the like portion 39 of rail 3 of section A is turned over so as tocontact with the pervious material 14 of section B.

It is to be particularly observed that section B, that is, the outsidesection of the closure, extends down far enough below section A that itsrail 5 rests tightly against the sill 31 and that it is held tightlyagainst the sill 31 by the pressure of the sash, of which the lower railis 26, bearing tightly against the shoulder 25 along the line 28. Thisconstruction insures a closure along the line 32, which is open on.ordinary and well known screens, and also insures a stability to theclosure, which is absent from ordinary closures and screens, because theordinary closure or screen although having the lower rail of the sashresting on the outside section thereof has that outside section up abovethe sill and free therefrom, the screen resting upon the inner section,that is, the section corresponding to applicants section A.

By reference to Figs. 1 and 2, it will be seen that the shoulder members24 and 25 do not extend the full length of the sections to which theyare attached, there being a cut out portion at 40 on section B, andanother cut out portion at 41 on section A. These cut out portions arenecessary because the shoulder members 24 and 25 must be constructed soas not to interfere with the front stops, as 34 and 35 as shown in Fig.3.

The amount cut away is meely sufficient to allow enough of the rails as2 and 7 to abut the front stops, as 34 and 35, so as to keep the screenproperly in place and close the opening at these points.

By Fig. 6 a modified form of closure is shown. This modified formconsists of two sections C and D comparable with B and A of, Fig. 1. Inthis form, the rails as 42, 43, 44, and 45, and the corresponding railsupon sections D, are not Initered at the corners as in the form shown byFigs. 1 and 2, but are butt jointed, as at 46 and 47. This is donebecause the rails, such as 44, are formed with a projection 43substantially, approximately circular in cross-section, as best shown inFig. 7. The mating rail on section D is likewise formed but, of course,reversely as shown in Fig. '7 with projection 49. A tie and slide member50 is fitted into the projections 48 and 49 and due to its shape,somewhat like a dumb-bell, it retains the sections close together andalso furnishes a slide for one section to move relatively to the other.

In Fig. 8 a modified form of construction is shown in which the rails as1 and 5 are pressed or rolled with projections 52 and 53 respectivelythereon over which members 15 and 17 are placed.

Fig. 8 also shows a modified form of inter-engaging rails between thesections as A and B. In this form a dovetail grooved member54 isattached to a rail, as l, and a dovetail tongue 55 is attached to arail, as 5. The tongue 55 and the groove 54 inter-engage so that the twosections will not move relatively transversely, but may be slidlongitudinally.

In Fig. 9 another method of attaching the pervious material to theclosure sections is shown. In the form of closure as shown by Fig. 6,rails as 42, 43, 44 and 45 may have a portion as 56,

shown in Fig. 9, on the inner edges thereof turned upwardly as viewed inFig. 6, that is, upwardly from the plane of the paper, and the railssuch as 57, 58, 59, and 60 of section D may have the edges, as 61 of 57,as shown in Fig. 9 turned downwardly, that is, downwardly from the planeof the paper, as shown in Fig. 6. With such a construction the perviousmaterial, as 62 and 63 in Fig. 9, may be attached to projections, as 56and 61, by means of channels, as 64 and 65, which when placed over theprojections, as 56 and 61, will when the pervious material istherebetween fit so tightly that they will remain in place and securelyhold the pervious material.

In Fig. 10 a closure has been illustrated formed of two sections, E andF, which are of some considerable thickness, that is, they are not asthin as the ordinary sheet metal sections as shown in Fig. 1 to 9inclusive. In such case a strip 65 is attached to one of the sections E,so that the end corner of that section will be on a line with the line66 of section F, so that both section F and section E will properly bearagainst the front stops 67 and 68. In order to have a closure of theform shown in Fig. 10 properly bear upon the sill so that the section Fwill bear against the shoulder 69 of the sill '70 and the section Ewhich is the outside section of the screen will properly bear uponsurface '71 of the sill, it is necessary to bevel the lower surface ofsection F and the bottom of section E, as shown in Fig. 11 at 72, sothat the lower surface of F will not bear upon the surface 71 of thesill '70, but the closure will bear along the line '73, that is, alongthe inside line of the outside section E. By such construction aclosure, as one composed of sections E and F, provided with theshoulders, such as 24 and 25, as shown in Fig. 5, and bearing againstthe front stops 67 and 68, as shown in Fig. 10, would i completely closethe opening of the window in which it is placed, because the insidesection F ,would bear along the surface 69 of the sill 70,

Although I have particularly described a preferred form and otherembodiments of my invention and explained the principle and mode ofoperation and construction thereof, nevertheless, I desire to have itunderstood that the forms selected are merely illustrative but do notexhaust the possible physical embodiments of the idea of meansunderlying my invention.

What I claim as new and desire to secure by Letters Patent of the UnitedStates, is:

1. In a closure, in combination: two covered frames slidinglycooperating, the two frames together being of a thickness less than thedistance between the front and back stops for the lower sash of awindow, one of said frames extending downwardly farther than the otherwhereby it may be made the outside frame of the closure and close thespace between it and the sill of a window opening in which it is placedand means at the top of each frame whereby no spaces exist betweeneither frame and the lower rail of the lower sash of a window in whichthe closure is placed.

2. In a closure, in combination: two frames, each including a top, abottom, and two side rails, the bottom rail of one frame being slightlywider than the bottom rail of the other frame; means positioned betweenthe frames and cooperating with each frame whereby one frame isslidingly attached to the other frame; pervious material positioned oneach frame; means, including rod-like members attached to the rails andtrough-like members adapted to be pushed in place thereon formaintaining the pervious material in place; a pervious materialcontacting portion on a side rail of each frame for contasting thepervious material of the other frame; an end extension on one side railof one frame for contact with a front stop of an opening in line withthe other frame; shoulder members attached to the top rail of each frameformed to bear against the inside face of the lower rail of a windowsash positioned in the opening where the closure is used, said shouldermembers each having a cut away portion at their outside ends to receivethe front stops of an opening.
